almost right it realy means he want a picture

slowing the blower will remove more humidity but imo should not be less then 80 percent then the rated cfms needed

if to much can cause ice problem and flood back on the compressor this is why IBM is right the refrigerant needs to be checked.

it is also important do have the proper static pressure at the needed cfm and slowing the blower to compensate is a bandade not a proper fix
pictures pictures and more pictures will tell us a lot about the kind of job you recieved

Along those same lines though...I think at least one of the copper lines going into the house looks like it was crimped and then sautered (sp?)...think they just reused existing line and is that a problem?

Lets not go there right now

Your issue is noise a droning noise, you have to isolate it and see if it air noise or something else.

Sounds like it may be both air and outside unit transmitting noise through the refrigerant lines.

Looked at the same problem last week and it was the outside unit. droning noise is a good description.

Okay, I'm in process. Just racing around trying to find the dad-blamed camera (one time in my life I can't find it).

Thank you thank you thank you! I feel better hearing you say that you sell Goodmans and they are a good brand. I take it you don't normally have complaints about inside noise level?

One final question about effectiveness...my husband says he doesn't want the blower speed reduced because he is convinced the system won't cool as well/quickly with reduced blower speed (I think it's a complex from having a weak old A/C for years). Will it? Why is the higher blower speed provided?

Also, on this model, I assume it does not automatically adjust speed. Why are the other speeds provided?

Speeds are selected based on the need of the home. If a load calcualtion is done properly, your cooling needs (BTU's) could be different from your heating needs (BTU's). Therefore, the speeds are should be set up appropriately. Your air handler could actually handle up to a 4 ton unit and down to a 3 ton unit. Thats why it is so important to make sure that the air flow is set up properly before messing with the refrigerant charge.

A slower blower in AC mode will remove more humidity. Which equals comfort.
A huge rush of air in cooling mode will cool the air around you, but not remove much humidty from the air...which equals crappy comfort levels.

Look it's easy to find out if it's air flow related or freon pumping through the lines. Heres what you do go outside and "hopefully" you have a disconnect on your outside condenser well flip that sucker off, if no disconnect well kill the breaker to the outside unit and then go back in and turn on the unit inside to the fan on position on the thermostat and see if you still hear the noise.
